COMBINED CONGEALER AND SIZER.

Application filed December My invention relates to a combilned congcaler and sizer, and the obJects of mylinvention are: first, to provide an apparatus for congealing liquids, more particularly agar; second, to provide a congealing apparatus of this class which sizes the material as it leaves the congealer; third, to provide a novelly constructed andrarranged congealer and sizer for agar and the like; zfourth, to provide a congealer which is almost instantaneous in its action; fifth, to provide a means for making congealed material in short cylindrical portions; sixth, kto provide a novelly constructed congealer and sizer, and seventh, to provide a combined congealer and sizer of this class which is very simple and economical of con-- Y struction, durable, eiicient in its action, and which will not readily deteriorater` or get out oforder. nl

ith'these and other objects in view, as will appear hereinafter, my invention consists of certain novelfeatures of construction, combination and arrangement of parts and portions, as will be hereinafter described in detail and particularly 'set'forth inthe appen'dedclaims, reference being had to the accompanying drawings andto the characters of reference thereon, which forma part of this application, in which :i i Figure 1 is a longitudinal sectional view of thecongealer andsizer, showing some of the parts in elevation. tol facilitate the illustration; Fig. 2 is an end view of the operating mechanism and congealer and sizer from-the line 2 2 of Fig. 1; Fig.'3 is a `sectional' vieW on an enlarged scale through 3 3 of Fig. 1.; Fig. 1l is an end view on an enlarged scale from the line 4 4 of Fig, 1, showing a portion broken away and in section to facilitate the illustration, and Fig. 5 is a top or plan view. of theoutlet end of the congealer and sizer from theline 5 5 of 1.

Like characters of reference referk to simi-V lar parts and portions throughout theseveral views of the drawings.

Y The cylindrical L,casing 1, spout 2, face plates 3 and 1l, tubes 5, knife 6, support 7, shaft,` 8, valve member `9. head member 10, revolving packing` 11, stuilin box ygland 12, ma,- terial inlet 13, pressure gage lll, water inlet 15, water3outlety16, thermometer 17,`main driveshaft 18, gearing support 19, bearings 2O and 21, gear 22, pinion 23, and drive pulley ll, 1926. Serial No. 152,716.

24, constitute the principal parts and portions of my combined congealer and sizer.

AThe casingpl isla hollow cylindrical casing threaded externally atr its head end and adapted to .lit into the th readed portion of the head member 10. Around its `opposite end is a clamp band 1, which isa band of circular form adapted toA fit aroundthe end and provided with extended loop portions lb and 1C through which a bolt 1d extends. This clamp band 1a is for the purpose of securingfthe spout 2in position relative to the cylinder l,

the spout being` provided with an angular flange' portion 2, which fitsin betweenv the band andthe end of the cylinder 1, thus providing means for securely clamping the spout member 2 at the outlet end of the cylinder 1. This cylinder 1 is internally threaded at its opposite end, into which are screwed the face plates 3 and 1l, ltigidly secured in these face plates 3 and 4 is a plurality of tubes 5, as shown best in Figs, 1A` 3 and l of the draws ings. `Mounted centrallyiin the casing 1 isa shaft 8, .which extends longitudinally there' through,and at the outlet end extends some distance beyond the face plate di. Secured on this shaft is support member 7,;which is provided'with a tension spring 7a andfwith ballfbearings Zh tending to. hold said supl port agains't'the end of the face platev and revolvingwiththe -shaft 8. j Secured on this support? is a knife member 6, which extends outwardly to pass the louter row of tubes in, f

the baseplate 4L. This knife 6 is provided with a. hub portion` 6a. which is rigidly `se-y cured v.on the support 7. The shaft 8 is secured-in the end of the main shaft 18, and theJ main shaft 18 entendsinto the base plate 3 and is journaled thereon. Mounted against the end ofthe base plate S on the outer side is a disc provided with a Lslot 9a extending `from near its middle to near its periphery, as shown best in Fig. 3 of .the drawings, thus providing a' valve over the ends `of the tubes 5. This valve 9 is secured to the shaft r18 rby means of akeylQ so that the valve 9`revolves with the shaftsv 18 and 8, sothat the 'slot 9 passes over the ends yof ther-tubes 5thepasing 1, base plate 3, head 1G being station? ary. The valve 9 isygln'ovidedavith an eX- tendedl ub portion 9b, which isthreaded eirternally andv uponlwhich,is'mounted a packf ingmember l1, which'extends outwardly and is adapted to revolve iu the head 10. Between this packing member 11 and the head 1() is provided a packing 12a supported by the packing gland 12. Mount-ed in the upper side of the head is the material to be congealed inlet 13, which is provided with a pressure gage 14 for determining the amount of pressure the material is under in its passage to the congealer. The casing 1 .1s provided with a cold water inlet 15 near its outlet end and with a water outlet 16 toward its A h-ead end, thus providing for circulating the cold wat-er around the tubes 5. The shaft 18 is provided with a clutch 18a of any conven tional form. Around the shaft 8 is a spur gear 22, which meshes with the spur 1pinion 23 mounted on a secondary shaft 24a on which is mounted a driven pulley 2st upon which is a belt connected with any power mechanism.

The 4operation of my apparatus is as follows:

The agar, or other substance to be con gealed, is passed through the inlet conductor 18 into the' head 10 between the valve 9 and the packing member 11 in a hot liquidstate, the pressure being determined by the pres sure gage le and the valve 9 revolving, the material passes through the slot 9L into the tubes 5 and passes through the tubes, the cold water coming in through the tube 15 circulating around among the tubes and out through the out-let 16. The material is immediately congealed in the tubes and passes out under pressure at the outlet end. As it passes out the knife 6 cuts it olf so that it is formed in a plurality of short, cylindrical portions and dropped down onto the spout 2, which conducts it from the apparatus, it being noted that the length of the cylindrical portions depends upon the pressure the material is under in its passage through the congealer. v y
